Hamilton 7656-01, Model 1710 Removable Needle Syringes

Syringe terminations play a critical role in precision fluid handling. These specialized attachments determine how needles are integrated with syringe barrels, impacting dead volume, compatibility, and application versatility. From the precision of the Removable Needle termination to the efficiency of the Luer Tip, each termination offers unique benefits. Consideration of factors like dead volume, autoclavability, and customization options guides the selection of the most suitable termination for specific laboratory tasks. In scientific and medical research, the choice of syringe termination holds significance beyond mere functionality. It directly influences the accuracy of experiments, the reliability of results, and the efficiency of laboratory workflows. By carefully assessing the demands of each application and understanding the advantages of various terminations, researchers can ensure seamless, fluid manipulation, precise measurements, and optimal performance in their endeavors.

We offer a diverse range of Hamilton needle point styles tailored for specific syringe and needle product applications. Selecting the right needle point style ensures optimal performance in various scenarios. Point Style 2 has been historically favored for manual GC injections for its sharp, beveled, and curved design, ensuring efficient septum penetration while minimizing coring. With the introduction of Hamilton's latest GC septa, Point Style AS has shown remarkable results, extending septa lifespan by up to 10-fold. Regarding manual HPLC injections, the Point Style 3 needle with a blunt tip is recommended for use with 22 gauge injection valves and sample pipetting. Drawing samples efficiently is essential, and for cases where you need to extract the very last drop from a vial, Point Style 3 or AS is recommended as they reach the bottom. Animal injections demand the sharpest possible needle, making Point Style 4 at a 12° bevel the go-to option. A vertical bevel angle, such as 30° or 45°, is suggested for more precise applications or when injection site depth is critical.
